Does natural casing contain an allergen?
It depends on how it was made. Open Food Facts does not link natural casing to an allergen, and Bravoora’s label checker does not read the name as one. The label must name any allergen it carries.
Is natural casing vegan?
No. Natural casing is not vegan: it comes from an animal. It is not vegetarian either.
A pack can differ from the usual recipe: the app reads the label in your hand.

An allergen is stated only when two of three checks agree: the Open Food Facts record, Bravoora’s label checker, and the ingredient’s own name or family (oat flour is oats, a cheese is milk). Every name where they disagree waits for a person to review it.
